目的:探讨急性心肌梗死不同killip分级患者QRS积分与QT间期离散度之间的相关性。方法:选取ST段抬高型AMI患者66例,按killip分级分为Ⅰ、Ⅱ、Ⅲ和Ⅳ组,分别在AMI发生后第3天测定QRS积分及QTd,取得数值,对比分析三者之间的联系。结果:四组AMI患者QT间期的增大与QRS积分的增加密切相关,在killip分级越高的患者QRS积分与QTd关联度也越高。结论:随着AMI患者killip分级的增加,QTd与QRS积分呈正相关。
OBJECTIVE: To investigate the correlation between QRS score and QT dispersion in patients with different Killip classification of acute myocardial infarction. Methods: Sixty-six patients with ST-segment elevation AMI were divided into three groups according to the killip score. The QRS score and QTd were measured on the third day after the onset of AMI, and the values were obtained. Contact. Results: The increase of QT interval in four groups of patients with AMI was closely related to the increase of QRS score. The higher the killip score, the higher the correlation of QRS score and QTd was. Conclusion: With the increase of killip grade in AMI patients, QTd positively correlated with QRS score.
